While renewable energies locally installed in buildings are increasing; there is a potential or even a need to store them to promote their self-consumption. Being efficient, modular and scalable, reversible Solid Oxide Cell (rSOC) technology can play a key role. Works undertaken in the frame of the REFLEX European project are presented, starting with the optimization of each individual component, ie. cells, stacks and BoP components such as power electronics. With the support of modelling activities, the rSOC based system, made of 3 modules of 4 stacks each, coupled with a battery storage has been designed in such a way to ensure achieving maximum efficiency, while still operating the system in safe and lifetime-optimal conditions. The site where the system will be installed has been prepared. Furthermore, techno-economic simulations have been carried out to evaluate market driven requirements on system sizing and costs to be competitive with other storage solutions.
